Question

我试图在我的heroku发行版上进行迁移。我得到这个错误：

rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

PG::UndefinedTable: ERROR:  relation "plants" does not exist
: ALTER TABLE "images" ADD CONSTRAINT "fk_rails_d5e1aedcb5"
FOREIGN KEY ("plant_id")
REFERENCES "plants" ("id")

我的一些桌子经过，但不是这一个，我不确定这里甚至会发生什么。它适用于开发，但不适用于生产。

这是我的架构文件：

另外，我的应用程序被推送到Heroku，但是当我去'sign_up'时，我从heroku日志中得到错误：

2016-05-22T07:53:31.678059+00:00 app[web.1]: ActionView::Template::Error (undefined method `firstname' for #<User:0x007fa667e33798>):

任何人都可以帮我解决这个问题吗？非常感谢:)）

Answer 1

显然其中一个迁移文件丢失了如果迁移目录已满或与数据库不一致，则可以使用rake db:schema:load直接创建整个数据库。

Answer 2

感谢评论中的@xyious。不知何故，一些迁移被删除，我不知道。正在运行heroku run rake db:schema:load 解决了这个问题。
